A light unit used in train tunnels is readily mountable and removable from a mounting bracket. The mounting bracket allows the battery backup system and light engine to be gravity mounted in manner that allows for quick and easy mounting and removal while also resisting vibrations and wind. A quick disconnect fitting can be used with the power cord to allow the units to be removed and replaced as needed. The light unit integrates the light engine with a battery backup system so that the entire light and battery unit is removed and replaced when necessary.
